The present invention relates to a lighting device, in particular, a device which includes one or more solid state light emitters (e.g., light emitting diodes) and one or more luminescent materials (e.g., one or more phosphors). The present invention is also directed to lighting methods.
A large proportion (some estimates are as high as one third) of the electricity generated in the United States each year goes to lighting. Accordingly, there is an ongoing need to provide lighting which is more energy-efficient. It is well-known that incandescent light bulbs are very energy-inefficient light sources—about ninety percent of the electricity they consume is released as heat rather than light. Fluorescent light bulbs are more efficient than incandescent light bulbs (by a factor of about four) but are still quite inefficient as compared to solid state light emitters, such as light emitting diodes.
In addition, as compared to the normal lifetimes of solid state light emitters, incandescent light bulbs have relatively short lifetimes, i.e., typically about 750–1000 hours. In comparison, the lifetime of light emitting diodes, for example, can generally be measured in decades. Fluorescent bulbs have longer lifetimes (e.g., 10,000–20,000 hours) than incandescent lights, but provide less favorable color reproduction.
Color reproduction is typically measured using the Color Rendering Index (CRI). CRI is a relative measurement of how the color rendition of an illumination system compares to that of a blackbody radiator, i.e., it is a relative measure of the shift in surface color of an object when lit by a particular lamp. The CRI equals 100 if the color coordinates of a set of test colors being illuminated by the illumination system are the same as the coordinates of the same test colors being irradiated by the blackbody radiator. Daylight has the highest CRI (of 100), with incandescent bulbs being relatively close (about 95), and fluorescent lighting being less accurate (70–85). Certain types of specialized lighting have relatively low CRI's (e.g., mercury vapor or sodium, both as low as about 40 or even lower). Sodium lights are used, e.g., to light highways. Driver response time, however, significantly decreases with lower CRI values (for any given brightness, legibility decreases with lower CRI).
Another issue faced by conventional light fixtures is the need to periodically replace the lighting devices (e.g., light bulbs, etc.). Such issues are particularly pronounced where access is difficult (e.g., vaulted ceilings, bridges, high buildings, traffic tunnels) and/or where change-out costs are extremely high. The typical lifetime of conventional fixtures is about 20 years, corresponding to a light-producing device usage of at least about 44,000 hours (based on usage of 6 hours per day for 20 years). Light-producing device lifetime is typically much shorter, thus creating the need for periodic change-outs.
Accordingly, for these and other reasons, efforts have been ongoing to develop ways by which solid state light emitters can be used in place of incandescent lights, fluorescent lights and other light-generating devices in a wide variety of applications. In addition, where solid state light emitters are already being used, efforts are ongoing to provide solid state light emitter-containing devices which are improved, e.g., with respect to energy efficiency, color rendering index (CRI), contrast, efficacy (1 m/W), and/or duration of service.
Light emitting diodes are well-known semiconductor devices that convert electrical current into light. A wide variety of light emitting diodes are used in increasingly diverse fields for an ever-expanding range of purposes.
More specifically, light emitting diodes are semiconducting devices that emit light (ultraviolet, visible, or infrared) when a potential difference is applied across a p-n junction structure. There are a number of well-known ways to make light emitting diodes and many associated structures, and the present invention can employ any such devices. By way of example, Chapters 12–14 of Sze, Physics of Semiconductor Devices, (2d Ed. 1981) and Chapter 7 of Sze, Modern Semiconductor Device Physics (1998) describe a variety of photonic devices, including light emitting diodes.
The commonly recognized and commercially available light emitting diode (“LED”) that is sold (for example) in electronics stores typically represents a “packaged” device made up of a number of parts. These packaged devices typically include a semiconductor based light emitting diode such as (but not limited to) those described in U.S. Pat. Nos. 4,918,487; 5,631,190; and 5,912,477; various wire connections, and a package that encapsulates the light emitting diode.
As is well-known, a light emitting diode produces light by exciting electrons across the band gap between a conduction band and a valence band of a semiconductor active (light-emitting) layer. The electron transition generates light at a wavelength that depends on the band gap. Thus, the color of the light (wavelength) emitted by a light emitting diode depends on the semiconductor materials of the active layers of the light emitting diode.
Although the development of solid state light emitters, e.g., light emitting diodes, has in many ways revolutionized the lighting industry, some of the characteristics of solid state light emitters have presented challenges, some of which have not yet been fully met. For example, the emission spectrum of any particular light emitting diode is typically concentrated around a single wavelength (as dictated by the light emitting diode's composition and structure), which is desirable for some applications, but not desirable for others, (e.g., for providing lighting, such an emission spectrum provides a very low CRI).
Because light that is perceived as white is necessarily a blend of light of two or more colors (or wavelengths), no single light emitting diode can produce white light. “White” light emitting diodes have been produced which have a light emitting diode pixel formed of respective red, green and blue light emitting diodes. Other “white” light emitting diodes have been produced which include (1) a light emitting diode which generates blue light and (2) a luminescent material (e.g., a phosphor) that emits yellow light in response to excitation by light emitted by the light emitting diode, whereby the blue light and the yellow light, when mixed, produce light that is perceived as white light.
In general, the 1931 CIE Chromaticity Diagram (an international standard for primary colors established in 1931), and the 1976 CIE Chromaticity Diagram (similar to the 1931 Diagram but modified such that similar distances on the Diagram represent similar perceived differences in color) provide useful reference for defining colors as weighted sums of colors.
A wide variety of luminescent materials (and structures which contain luminescent materials, known as lumiphors or luminophoric media, e.g., as disclosed in U.S. Pat. No. 6,600,175, the entirety of which is hereby incorporated by reference) are well-known and available to persons of skill in the art. For example, a phosphor is a luminescent material that emits a responsive radiation (e.g., visible light) when excited by a source of exciting radiation. In many instances, the responsive radiation has a wavelength which is different from the wavelength of the exciting radiation. Other examples of luminescent materials include scintillators, day glow tapes and inks which glow in the visible spectrum upon illumination with ultraviolet light.
Luminescent materials can be categorized as being down-converting, i.e., a material which converts photons to a lower energy level (longer wavelength) or up-converting, i.e., a material which converts photons to a higher energy level (shorter wavelength).
Inclusion of luminescent materials in LED devices has been accomplished by adding the luminescent materials to a clear plastic encapsulant material (e.g., epoxy-based or silicone-based material) as discussed above, for example by a blending or coating process.
For example, U.S. Pat. No. 6,963,166 (Yano '166) discloses that a conventional light emitting diode lamp includes a light emitting diode chip, a bullet-shaped transparent housing to cover the light emitting diode chip, leads to supply current to the light emitting diode chip, and a cup reflector for reflecting the emission of the light emitting diode chip in a uniform direction, in which the light emitting diode chip is encapsulated with a first resin portion, which is further encapsulated with a second resin portion. According to Yano '166, the first resin portion is obtained by filling the cup reflector with a resin material and curing it after the light emitting diode chip has been mounted onto the bottom of the cup reflector and then has had its cathode and anode electrodes electrically connected to the leads by way of wires. According to Yano '166, a phosphor is dispersed in the first resin portion so as to be excited with the light A that has been emitted from the light emitting diode chip, the excited phosphor produces fluorescence (“light B”) that has a longer wavelength than the light A, a portion of the light A is transmitted through the first resin portion including the phosphor, and as a result, light C, as a mixture of the light A and light B, is used as illumination.
As noted above, “white LED lights” (i.e., lights which are perceived as being white or near-white) have been investigated as potential replacements for white incandescent lamps. A representative example of a white LED lamp includes a package of a blue light emitting diode chip, made of gallium nitride (GaN), coated with a phosphor such as YAG. In such an LED lamp, the blue light emitting diode chip produces a blue emission and the phosphor produces yellow fluorescence on receiving that emission. For instance, in some designs, white light emitting diodes are fabricated by forming a ceramic phosphor layer on the output surface of a blue light-emitting semiconductor light emitting diode. Part of the blue ray emitted from the light emitting diode chip passes through the phosphor, while part of the blue ray emitted from the light emitting diode chip is absorbed by the phosphor, which becomes excited and emits a yellow ray. The part of the blue light emitted by the light emitting diode which is transmitted through the phosphor is mixed with the yellow light emitted by the phosphor. The viewer perceives the mixture of blue and yellow light as white light.
As also noted above, in another type of LED lamp, a light emitting diode chip that emits an ultraviolet ray is combined with phosphor materials that produce red (R), green (G) and blue (B) light rays. In such an “RGB LED lamp”, the ultraviolet ray that has been radiated from the light emitting diode chip excites the phosphor, causing the phosphor to emit red, green and blue light rays which, when mixed, are perceived by the human eye as white light. Consequently, white light can also be obtained as a mixture of these light rays.
Designs have been provided in which existing LED component packages and other electronics are assembled into a fixture. In such designs, a packaged LED is mounted to a circuit board, the circuit board is mounted to a heat sink, and the heat sink is mounted to the fixture housing along with required drive electronics. In many cases, additional optics (secondary to the package parts) are also necessary.
In substituting solid state light emitters for other light sources, e.g., incandescent light bulbs, packaged LEDs have been used with conventional light fixtures, for example, fixtures which include a hollow lens and a base plate attached to the lens, the base plate having a conventional socket housing with one or more contacts which are electrically coupled to a power source. For example, LED light bulbs have been constructed which comprise an electrical circuit board, a plurality of packaged LEDs mounted to the circuit board, and a connection post attached to the circuit board and adapted to be connected to the socket housing of the light fixture, whereby the plurality of LEDs can be illuminated by the power source.
There is an ongoing need for ways to use solid state light emitters, e.g., light emitting diodes, to provide white light in a wider variety of applications, with greater energy efficiency, with improved color rendering index (CRI), with improved efficacy (1 m/W), and/or with longer duration of service.
There exist “white” LED light sources which are relatively efficient but which have poor color rendering, typically having CRI values of less than 75, and which are particularity deficient in the rendering of red colors and also to a significant extent deficient in green. This means that many things, including the typical human complexion, food items, labeling, painting, posters, signs, apparel, home decoration, plants, flowers, automobiles, etc. exhibit odd or wrong color as compared to being illuminated with an incandescent light or natural daylight.
So called “warm white” LEDs have a more acceptable color temperature for indoor use, and good CRI, but their efficiency is much less then half that of the standard “white” LEDs.
Colored objects illuminated by RGB LED lamps frequently do not appear in their true colors. For example, an object that reflects only yellow light, and thus that appears to be yellow when illuminated with white light, will appear black when illuminated with light having an apparent yellow color, produced by the red and green LEDs of an RGB LED fixture. Such lamps, therefore, are considered to provide poor color rendition, particularly when illuminating various settings such as a theater stage, television set, building interior, or display window. In addition, currently available green LEDs are relatively inefficient, and thus limit the efficiency of such lamps.
Employing LEDs having a wide variety of hues would similarly necessitate use of LEDs having a variety of efficiencies, including some with low efficiency, thereby reducing the efficiency of such systems.
There is therefore a need for a high efficiency white light source that combines the efficiency and long life of white LEDs (i.e., which avoids the use of relatively inefficient light sources) with an acceptable color temperature and good color rendering index and a wide gamut.
In accordance with the present invention, it has unexpectedly been found that surprisingly high CRI can be obtained, while obtaining surprisingly high efficacy, by (1) illuminating one or more solid state light emitters which emit light having a dominant wavelength in the range of from 430 nm to 480 nm, (2) exciting one or more lumiphors which emit light having a dominant wavelength in the range of from 555 to 585 and (3) illuminating one or more solid state light emitters which emit light having a having a dominant wavelength in the range of from 600 nm to 630 nm such that:
The expression “dominant wavelength”, is used herein according to its well-known and accepted meaning to refer to the perceived color of a spectrum, i.e., the single wavelength of light which produces a color sensation most similar to the color sensation perceived from viewing light emitted by the light source (i.e., it is roughly akin to “hue”), as opposed to “peak wavelength”, which is well-known to refer to the spectral line with the greatest power in the spectral power distribution of the light source. Because the human eye does not perceive all wavelengths equally (it perceives yellow and green better than red and blue), and because the light emitted by many solid state light emitter (e.g., LEDs) is actually a range of wavelengths, the color perceived (i.e., the dominant wavelength) is not necessarily equal to (and often differs from) the wavelength with the highest power (peak wavelength). A truly monochromatic light such as a laser has the same dominant and peak wavelengths.

In some embodiments according to the present invention:
The present invention is further directed to an enclosure comprising an enclosed space and at least one lighting device as described herein, wherein if current is supplied to the first power line, the lighting device illuminates at least a portion of the enclosed space.
The present invention is further directed to a structure comprising a surface and at least one lighting device as described herein, wherein if current is supplied to the first power line, the lighting device would illuminate at least a portion of the surface.
The present invention is further directed to an illuminated area, comprising at least one item selected from among the group consisting of swimming pool, a room, a warehouse, an indicator, a road, a vehicle, a road sign, a billboard, a ship, a toy, an electronic device, a boat, an aircraft, a stadium, a tree, a window, a yard and a lamppost, having mounted therein or thereon at least one lighting device as described herein.
In some embodiments according to the present invention, the lighting device further comprises at least one additional white solid state light emitter, i.e., a device which emits light which is perceived as white or near white (e.g., a packaged LED which contains at least one light emitting diode chip and/or at least one lumiphor which, when illuminated and/or excited, emits a combination of light which is perceived as white or near white, such as a packaged LED which consists of a blue light emitting diode chip and a yellow lumiphor), in which the one or more additional white solid state light emitters each emit a combination of light which has x, y color coordinates which define a point which is outside the first area on a 1931 CIE Chromaticity Diagram enclosed by the first, second, third, fourth and fifth line segments as defined above.
In some embodiments according to the present invention, the sub-mixture of light is produced by a first sub-group of light emitting diodes, a first sub-group of lumiphors, a second sub-group of light emitting diodes and a second sub-group of lumiphors, wherein:
In some embodiments according to the second aspect of the present invention, the first and second groups of solid state light emitters are illuminated by supplying current to the first power line.
The solid state light emitters can be saturated or non-saturated. The term “saturated”, as used herein, means having a purity of at least 85%, the term “purity” having a well-known meaning to persons skilled in the art, and procedures for calculating purity being well-known to those of skill in the art.
Aspects related to the present invention can be represented on either the 1931 CIE (Commission International de I'Eclairage) Chromaticity Diagram or the 1976 CIE Chromaticity Diagram.
The CIE Chromaticity Diagrams map out the human color perception in terms of two CIE parameters x and y (in the case of the 1931 diagram) or u′ and v′ (in the case of the 1976 diagram). For a technical description of CIE chromaticity diagrams, see, for example, “Encyclopedia of Physical Science and Technology”, vol. 7, 230–231 (Robert A Meyers ed., 1987). The spectral colors are distributed around the edge of the outlined space, which includes all of the hues perceived by the human eye. The boundary line represents maximum saturation for the spectral colors. As noted above, the 1976 CIE Chromaticity Diagram is similar to the 1931 Diagram, except that the 1976 Diagram has been modified such that similar distances on the Diagram represent similar perceived differences in color.
In the 1931 Diagram, deviation from a point on the Diagram can be expressed either in terms of the coordinates or, alternatively, in order to give an indication as to the extent of the perceived difference in color, in terms of MacAdam ellipses. For example, a locus of points defined as being ten MacAdam ellipses from a specified hue defined by a particular set of coordinates on the 1931 Diagram consists of hues which would each be perceived as differing from the specified hue to a common extent (and likewise for loci of points defined as being spaced from a particular hue by other quantities of MacAdam ellipses).
Since similar distances on the 1976 Diagram represent similar perceived differences in color, deviation from a point on the 1976 Diagram can be expressed in terms of the coordinates, u′ and v′, e.g., distance from the point=(Δu′2+Δv′2)1/2, and the hues defined by a locus of points which are each a common distance from a specified hue consist of hues which would each be perceived as differing from the specified hue to a common extent.
The chromaticity coordinates and the CIE chromaticity diagrams illustrated in
The chromaticity coordinates (i.e., color points) that lie along the blackbody locus obey Planck's equation: E(λ)=A λ−5/(e(B/T)−1), where E is the emission intensity, λ is the emission wavelength, T the color temperature of the blackbody and A and B are constants. Color coordinates that lie on or near the blackbody locus yield pleasing white light to a human observer. The 1976 CIE Diagram includes temperature listings along the blackbody locus. These temperature listings show the color path of a blackbody radiator that is caused to increase to such temperatures. As a heated object becomes incandescent, it first glows reddish, then yellowish, then white, and finally blueish. This occurs because the wavelength associated with the peak radiation of the blackbody radiator becomes progressively shorter with increased temperature, consistent with the Wien Displacement Law. Illuminants which produce light which is on or near the blackbody locus can thus be described in terms of their color temperature.
CRI is a relative measurement of how the color rendition of an illumination system compares to that of a blackbody radiator. The CRI equals 100 if the color coordinates of a set of test colors being illuminated by the illumination system are the same as the coordinates of the same test colors being irradiated by the blackbody radiator.
The present invention may be more fully understood with reference to the accompanying drawings and the following detailed description of the invention.
The expression “430 nm to 480 nm solid state light emitter” means any solid state light emitter which, if illuminated, would emit light having a dominant wavelength in the range of from about 430 nm to about 480 nm.
The expression “555 nm to 585 nm lumiphor” means any lumiphor which, if excited, would emit light having a dominant wavelength in the range of from about 555 nm to about 585 nm.
The expression “600 nm to 630 nm solid state light emitter” means any solid state light emitter which, if illuminated, would emit light having a dominant wavelength in the range of from about 600 nm to about 630 nm.
The term “current”, as used in the expression “if current is supplied to the first power line” means electrical current which is sufficient to cause the 430 nm to 480 nm solid state light emitter(s) to emit light having a dominant wavelength in the range of from about 430 nm to about 480 nm, to cause the 555 nm to 585 nm lumiphor(s) to emit light having a dominant wavelength in the range of from about 555 nm to about 585 nm, and/or to cause the 600 nm to 630 nm solid state light emitter(s) to emit light having a dominant wavelength in the range of from about 600 nm to about 630 nm.
The expression “directly or switchably electrically connected” means “directly electrically connected” or “switchably electrically connected.”
A statement herein that one or more solid state light emitters are “electrically connected” to a power line means that current can be supplied to the solid state light emitter(s) by supplying current to the power line.
A statement herein that one or more switch is electrically connected to a power line means that current can flow through the power line if the switch (or switches) are closed, and current can be prevented from flowing through the power line if the switch (or one or more of the switches) is open.
A statement herein that two components in a device are “switchably electrically connected” means that there is a switch located between the two components, the switch being selectively closed or opened, wherein if the switch is closed, the two components are electrically connected, and if the switch is open (i.e., during any time period that the switch is open), the two components are not electrically connected.
The expression “illuminated”, as used herein when referring to a solid state light emitter, means that at least some current is being supplied to the solid state light emitter to cause the solid state light emitter to emit at least some light.
The expression “excited”, as used herein when referring to a lumiphor, means that at least some electromagnetic radiation (e.g., visible light, UV light or infrared light) is contacting the lumiphor, causing the lumiphor to emit at least some light.
The solid state light emitters used in the devices according to the present invention, and the lumiphor (or lumiphors) used in the devices according to the present invention, can be selected from among any solid state light emitters and lumiphors known to persons of skill in the art. Wide varieties of such solid state light emitters and lumiphors are readily obtainable and well known to those of skilled in the art, and any of them can be employed. For example, solid state light emitters and lumiphors which may be used in practicing the present invention are described in:

U.S. Provisional Patent Application No. 60/808,702, filed on May 26, 2006, entitled “Lighting Device” (inventors: Gerald H. Negley and Antony Paul van de Ven), the entirety of which is hereby incorporated by reference;
U.S. Provisional Patent Application No. 60/802,697, filed on May 23, 2006, entitled “Lighting Device and Method of Making” (inventor: Gerald H. Negley), the entirety of which is hereby incorporated by reference; and
U.S. Provisional Patent Application No. 60/839,453, filed on Aug. 23, 2006, entitled “LIGHTING DEVICE AND LIGHTING METHOD” (inventors: Antony Paul van de Ven and Gerald H. Negley), the entirety of which is hereby incorporated by reference.
Examples of types of such solid state light emitters include inorganic light emitting diodes and organic light emitting diodes, a variety of each of which are well-known in the art.
The one or more luminescent materials can be any desired luminescent material. The one or more luminescent materials can be down-converting or up-converting, or can include a combination of both types. For example, the one or more luminescent materials can be selected from among phosphors, scintillators, day glow tapes, inks which glow in the visible spectrum upon illumination with ultraviolet light, etc.
The one or more luminescent materials can be provided in any desired form. For example, the luminescent element can be embedded in a resin (i.e., a polymeric matrix), such as a silicone material or an epoxy.
The one or more lumiphors can individually be any lumiphor, a wide variety of which, as noted above, are known to those skilled in the art. For example, the or each lumiphor can comprise (or can consist essentially of, or can consist of) one or more phosphor. The or each of the one or more lumiphors can, if desired, further comprise (or consist essentially of, or consist of) one or more highly transmissive (e.g., transparent or substantially transparent, or somewhat diffuse) binder, e.g., made of epoxy, silicone, glass or any other suitable material (for example, in any given lumiphor comprising one or more binder, one or more phosphor can be dispersed within the one or more binder). For example, the thicker the lumiphor, in general, the lower the weight percentage of the phosphor can be. Depending on the overall thickness of the lumiphor, however, the weight percentage of the phosphor could be generally any value, e.g., from 0.1 weight percent to 100 weight percent (e.g., a lumiphor formed by subjecting pure phosphor to a hot isostatic pressing procedure).
The or each of the one or more lumiphors can, independently, further comprise any of a number of well-known additives, e.g., diffusers, scatterers, tints, etc.
In some embodiments according to the present invention, one or more of the light emitting diode chips can be included in a package together with one or more of the lumiphors, and the one or more lumiphor in the package can be spaced from the one or more light emitting diode chip in the package to achieve improved light extraction efficiency, as described in U.S. Provisional Patent Application No. 60/753,138, filed on Dec. 22, 2005, entitled “Lighting Device” (inventor: Gerald H. Negley), the entirety of which is hereby incorporated by reference.
In some embodiments according to the present invention, two or more lumiphors can be provided, two or more of the lumiphors being spaced from each other, as described in U.S. Provisional Patent Application No. 60/761,310, filed on Jan. 23, 2006, entitled “Shifting Spectral Content in LEDs by Spatially Separating Lumiphor Films” (inventors: Gerald H. Negley and Antony Van De Ven), the entirety of which is hereby incorporated by reference.
In some embodiments of the present invention, a set of parallel solid state light emitter strings (i.e., two or more strings of solid state light emitters arranged in parallel with each other) is arranged in series with a power line, such that current is supplied through the power line to each of the respective strings of solid state light emitter. The expression “string”, as used herein, means that at least two solid state light emitters are electrically connected in series. In some such embodiments, the relative quantities of solid state light emitters in the respective strings differ from one string to the next, e.g., a first string contains a first percentage of 430 nm to 480 nm solid state light emitters and a second string contains a second percentage (different from the first percentage) of 430 nm to 480 nm solid state light emitters. As a representative example, first and second strings each contain solely (i.e., 100%) 430 nm to 480 nm solid state light emitters, and a third string contains 50% 430 nm to 480 nm solid state light emitters and 50% 600 nm to 630 nm solid state light emitters (each of the three strings being electrically connected to a common power line). By doing so, it is possible to easily adjust the relative intensities of the light of the respective wavelengths, and thereby effectively navigate within the CIE Diagram and/or compensate for other changes. For example, the intensity of red light can be increased, when necessary, in order to compensate for any reduction of the intensity of the light generated by the 600 nm to 630 nm solid state light emitters. Thus, for instance, in the representative example described above, by increasing the current supplied to the third power line, or by decreasing the current supplied to the first power line and/or second power line (and/or by interrupting the supply of power to the first power line or the second power line), the x, y coordinates of the mixture of light emitted from the lighting device can be appropriately adjusted.
In some embodiments of the present invention, there are further provided one or more current adjusters directly or switchably electrically connected to one or more of respective strings of solid state light emitters, whereby the current adjuster can be adjusted to adjust the current supplied to one or more of the respective strings of solid state light emitters. In some of such embodiments, the current adjuster is automatically adjusted to maintain the mixture of light within ten MacAdam ellipses of at least one point on the blackbody locus on a 1931 CIE Chromaticity Diagram.
In some embodiments of the present invention, there are further provided one or more switches electrically connected to one or more of the respective strings, whereby the switch selectively switches on and off current to the solid state light emitter(s) on the respective string.
In some embodiments of the present invention, one or more current adjusters and/or one or more switches automatically interrupt and/or adjust current passing through one or more respective strings in response to a detected change in the output from the lighting device (e.g., an extent of deviation from the blackbody locus) or in accordance with a desired pattern (e.g., based on the time of day or night, such as altering the correlated color temperature of the combined emitted light).
In some embodiments of the present invention, there are further provided one or more thermistors which detect temperature and, as temperature changes, cause one or more current adjusters and/or one or more switches to automatically interrupt and/or adjust current passing through one or more respective strings in order to compensate for such temperature change. In general, 600 nm to 630 nm light emitting diodes get dimmer as their temperature increases—in such embodiments, fluctuations in intensity caused by such temperature variation can be compensated for.
In some lighting devices according to the present invention, there are further included one or more circuitry components, e.g., drive electronics for supplying and controlling current passed through at least one of the one or more solid state light emitters in the lighting device. Persons of skill in the art are familiar with a wide variety of ways to supply and control the current passed through solid state light emitters, and any such ways can be employed in the devices of the present invention. For example, such circuitry can include at least one contact, at least one leadframe, at least one current regulator, at least one power control, at least one voltage control, at least one boost, at least one capacitor and/or at least one bridge rectifier, persons of skill in the art being familiar with such components and being readily able to design appropriate circuitry to meet whatever current flow characteristics are desired. For example, circuitry which may be used in practicing the present invention is described in:
U.S. Provisional Patent Application No. 60/809,959, filed on Jun. 1, 2006, entitled “Lighting Device With Cooling” (inventors: Thomas G. Coleman, Gerald H. Negley and Antony Paul van de Ven), the entirety of which is hereby incorporated by reference;
U.S. Provisional Patent Application No. 60/809,595, filed on May 31, 2006, entitled “LIGHTING DEVICE AND METHOD OF LIGHTING” (inventor: Gerald H. Negley), the entirety of which is hereby incorporated by reference; and

In addition, persons of skill in the art are familiar with a wide variety of mounting structures for many different types of lighting, and any such structures can be used according to the present invention.
For example, fixtures, other mounting structures and complete lighting assemblies which may be used in practicing the present invention are described in:
U.S. Provisional Patent Application No. 60/752,753, filed on Dec. 21, 2005, entitled “Lighting Device” (inventors: Gerald H. Negley, Antony Paul van de Ven and Neal Hunter), the entirety of which is hereby incorporated by reference;

U.S. Provisional Patent Application No. 60/846,222, filed on Sep. 21, 2006, entitled “LIGHTING ASSEMBLIES, METHODS OF INSTALLING SAME, AND METHODS OF REPLACING LIGHTS” (inventors: Antony Paul van de Ven and Gerald H. Negley), the entirety of which is hereby incorporated by reference; and
U.S. Provisional Patent Application No. 60/809,618, filed on May 31, 2006, entitled “LIGHTING DEVICE AND METHOD OF LIGHTING” (inventors: Gerald H. Negley, Antony Paul van de Ven and Thomas G. Coleman), the entirety of which is hereby incorporated by reference.
In some lighting devices according to the present invention, there are further included one or more power sources, e.g., one or more batteries and/or solar cells, and/or one or more standard AC power plugs.
The lighting devices according to the present invention can comprise any desired number of solid state light emitters and lumiphors. For example, a lighting device according to the present invention can include 50 or more solid state light emitters, or can include 100 or more solid state light emitters, etc.
The sources of visible light in the lighting devices of the present invention can be arranged, mounted and supplied with electricity in any desired manner, and can be mounted on any desired housing or fixture. Skilled artisans are familiar with a wide variety of arrangements, mounting schemes, power supplying apparatuses, housings and fixtures, and any such arrangements, schemes, apparatuses, housings and fixtures can be employed in connection with the present invention. The lighting devices of the present invention can be electrically connected (or selectively connected) to any desired power source, persons of skill in the art being familiar with a variety of such power sources.
The solid state light emitters and lumiphors can be arranged in any desired pattern. In some embodiments according to the present invention, some or all of the 600 nm to 630 nm solid state light emitters are surrounded by five or six 430 nm to 480 nm solid state light emitters (some or all of which may or may not include 555 nm to 585 nm lumiphors), e.g., the 600 nm to 630 nm solid state light emitters and the 430 nm to 480 nm solid state light emitters are arranged in generally laterally arranged rows and spaced from one another substantially evenly, each row being laterally offset from the next adjacent (in a longitudinal direction) row by half the distance between laterally adjacent solid state light emitters, with, in most locations, two 430 nm to 480 nm solid state light emitters being located between each 600 nm to 630 nm solid state light emitter and its nearest neighbor in the same row, and with the 600 nm to 630 nm solid state light emitters in each row being offset from the nearest 600 nm to 630 solid state light emitter(s) in the next adjacent (in a longitudinal direction) row by one and a half times the distance between laterally spaced adjacent solid state light emitters. Alternatively or additionally, in some embodiments according to the present invention, some or all of the brighter solid state light emitters are placed closer to a center of the lighting device than the dimmer solid state light emitters.
The devices according to the present invention can further comprise one or more long-life cooling device (e.g., a fan with an extremely high lifetime). Such long-life cooling device(s) can comprise piezoelectric or magnetorestrictive materials (e.g., MR, GMR, and/or HMR materials) that move air as a “Chinese fan”. In cooling the devices according to the present invention, typically only enough air to break the boundary layer is required to induce temperature drops of 10 to 15 degrees C. Hence, in such cases, strong “breezes” or a large fluid flow rate (large CFM) are typically not required (thereby avoiding the need for conventional fans).
The devices according to the present invention can further comprise secondary optics to further change the projected nature of the emitted light. Such secondary optics are well-known to those skilled in the art, and so they do not need to be described in detail herein—any such secondary optics can, if desired, be employed.
The devices according to the present invention can further comprise sensors or charging devices or cameras, etc. For example, persons of skill in the art are familiar with, and have ready access to, devices which detect one or more occurrence (e.g., motion detectors, which detect motion of an object or person), and which, in response to such detection, trigger illumination of a light, activation of a security camera, etc. As a representative example, a device according to the present invention can include a lighting device according to the present invention and a motion sensor, and can be constructed such that (1) while the light is illuminated, if the motion sensor detects movement, a security camera is activated to record visual data at or around the location of the detected motion, or (2) if the motion sensor detects movement, the light is illuminated to light the region near the location of the detected motion and the security camera is activated to record visual data at or around the location of the detected motion, etc.
